2. Homemade solutions:

Before shopping for replacement bag, we recommend that first you understand why your bag twists.The primary cause of bag twisting is unbalanced weight distribution of the clubs and other items in your bag. If
weight distribution is to one side or another, the force of gravity
will tend to twist the bag until the weight is centered on the bags
points of contact. Other forces, such as straps are in play to resist
gravity's forces, but sometimes are not a match.So before buying a new bag, try the inexpensive ideas listed below (in the sequence listed)

Check
the weight distribution of your bag to see if the distribution can be
better balanced without sacrificing convenient access to your clubs.
Here's how:

Lay the bag on a flat surface with the part of the bag that will rest on the cart facing up.

Pick
up the bag with your fingers (one in inserted inside the top of the bag
and another at the upper edge of the bag's bottom.) If the bag twists,
the weight is not evenly distributed and the bag will tend to twist.

Adjust the bag's balance by moving items inside the bag. The easiest way is to move items around in the pockets.

As
a last resort, move some clubs to achieve a better balance. However, if
clubs are loose and can easily be moved, this solution may not work
because the balance point is constantly shifting.

The remaining
suggestions accommodate an imbalance of bag weight distribution by
providing more resistance to the forces of gravity that cause twist.

Check your bag to see if a cart strap or straps can conveniently be threaded through some bag strap or opening.

Fasten a bungee cord around some part of the frame (bottom part is better) and pull it tight.

Bungee
cord alternate #1: Thread the bungee cord through a strap or hole in
the bag. This is like a make-shift anti-twist bag sleeve. (A bottom
umbrella hole can work nicely.)

Bungee cord alternate #2: Fasten the bungee cord to the bag and then thread it through some portion of the cart frame.

Find some non-slip material (like used in kitchen cabinets) and glue it to the bottom of your bag.

You
might also be able to apply the same non-slip material to the cart
itself either on the bottom rest or inside the upper strap.

If
all of these solutions fail, you might look into buying a lighter bag
with a manufacturer's "no-twist" feature. One of these solutions should
work for your situation. I hope you have found these tips helpful in
making your golf experience more enjoyable.
